Disclosed is a portable storage system for asphalt and other like material that is required to be maintained at a particular constant heated temperature even in sub-zero ambient temperatures. The system may include an exterior covering over a frame to define an enclosure. The frame defines an interior space where an insulated tank resides. The tank is heated. The interior of the enclosure may be heated. Rails provided along a vertical surface of the enclosure and extending above the roof of the enclosure allow the entire system to be loaded as a roll-off load on a truck. A plurality of lugs with apertures therethrough extend beyond the exterior surface of the enclosure to enable the enclosure to be lifted by cranes and tied down during transport.

A vertical fluid storage tank including a body extending from a first end to a second end and including a substantially oval-shaped cross-section, a top wall connected to the first end of the body, a bottom wall connected to the second end of the body, at least one access opening positioned on the top wall configured for access to an interior cavity of the body, and at least one discharge valve connected to the body. The storage tank is configured to be arranged in at least two positions. The at least two positions include a first position in which the storage tank is arranged parallel to a surface, and a second position in which the storage tank is arranged perpendicular to the surface. A walkway may be positioned in the interior cavity of the body.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

A permanent on-site manhole casting system comprising a top, a main barrel, and a base. Each component consists of a ribbed plastic outer barrel and a ribbed plastic inner barrel with a plurality of plastic tie strips used to connect the said outer and inner barrels. A coupling mechanism consisting of a plastic outer coupling ring and a plastic inner coupling ring is welded to the coupling ends of the top, main barrel and base which connects the top, main barrel and base components. A concrete mixture is poured into the space between the coupled outer and inner barrels where the concrete is then allowed to set and cure and the filled form is then completely buried.

A plastic article useful as a riser for a septic tank or as a water tank article is comprised of a multiplicity of plastic rings which are attached vertically to each other at joints. Ring pairs which alternately have inward and outward sloping conical walls nest within each other for shipment or storage. A lid is shaped for use with the topmost ring to cover the opening irrespective of which conical shape the ring has.
